For your little ones, popping on their wellies and splashing about in Baltic temperatures seems like the best idea in the world - but for you, it's a potential freeze risk (or should we say, complaint risk?) waiting to happen. The Hatley fleece boot liners are the perfect add on to their cute little rain boots and will keep their toes cosy as they stomp around. Plus, they're easy to wash, so you'll have no worries when equipped with these.
